I have only passed 40 mph 3 times in the area I live in. I get up to 30 mph when the wind is with me. I passed 50 mph 3 times on my cross country trip. 57.7 is my all time top speed. I had to goal of passing 50 forever, now that I have I need to look to 60 mph. With that being said I was a bit scared a few days after I got to 57.7 just thinking about it.
